Antozonite is a variety of fluorite characterized by the presence of multiple inclusions containing elemental fluorine. When the crystals are crushed or broken, the elemental fluorine is released. It was hypothesized that beta radiation from uranium inclusions causes the continuous breakdown of calcium fluoride into calcium and fluorine atoms. The fluorine atoms combine to produce difluoride anions, and upon losing the extra electrons at a defect, fluorine gas is formed. Although antozonite can be slightly radioactive, there was no measurable activity of this specimen with the pancake tube in the GO-GMC-600.

The dimensions of the case are 31x21x35mm.
